' LIQUID-FUEL BURNER.

Application led May 19, 1925. Serial No. 31,285.

As heretofore constructed liquid fuel burners of the type to which my invention relates have been so made as to include a casing, a wick holder movable within the casing to adjust a wick carried thereby to position, and devices for shifting the position of the wick holder to correspondingly determine the position of the wick for use. Ordinarily, these wick holders have been provided with a plurality of apertures and corresponding intervening portions, and a pinion has been employed for engagement with this portion of the wick holder to eect the movement thereof. However, so far as l am aware it has been customary heretofore to apply the pinion or similar device to one portion only of the wick holder, whereby as will be appreciated there was a tendency to cause the wick holder to bind or wedge in the casing, and also to cause the outer portion of the wick to extend unevenly beyond the peripheral edge of they casing, resulting in an uneven flame in the use of the burner.

The object of my present invention is to overcome these disadvantages by the provision of actuating devices for the wick holder in the use of which the wick holder is simultaneously engaged at oppositely disposed portions thereof, whereby in adjusting the wick holder and its wick to position a uniform movement is imparted to the wick holder, and in adjusting the wick all the parts thereof project evenly beyond the periphenl portions of the casing, resulting ina frame of uniform height in the use of the burner.

To this end in carrying out the invention the wick holder is preferably provided in oppositely disposed portions thereof, with a plurality of apertures and intervening parts acting as racks to be engaged by suitable pinions, or otherwise, operated simultaneously through sets of gears and the necessary shafts for operating the same, these parts being exterior of the burner casing as will be hereinafter more particularly described.

1n the drawing Fig. 1 is an elevation and partial cross-section of a liquid fuel burner made in accordancewith my invention.

Fig. 2 is a partial plan and section of the same.

Fig. 3 is a sectional elevation illustrating the relationship between the wick holder 'and the pinions for operating the same, as employed on one side of the casing.

Fig. el is an elevation of the wick Aholder and wick carried thereby.

Fig. 5 is a sectional plan illustrating another form of the invent-ion.

Fig. 6 is a partial elevation of the form of the burner as shown in Fig. 5.

Referring to the drawings, and particularly to Figs. 1 to t, inclusive, in which I have illustrated one embodiment ofthe invention it will be seen that in carrying out the same the liquid fuel burner comprises a casing having a cylindrical wall 10, adapted to receive and contain a wick holder 1 These members as will be understood may be made from suitable sheet metal or other similar material in the customary manner.

In oppositely disposed positions as indi-' cated at 12, and 13, the wick holder 11 is provided with a plurality of apertures which with the intermediate portions of the wick holt er are adapted to function as racks, as will be hereinafter more particularly described. It will also be understood that the wickholder 11 is adapted in a suit-able manner to receive and carry a wick 14C.

In' a suitable position, that is, at a predetermined elevation. the wall is tted with a'housing 15. l/Vithin this housing 15 there is an end bearing or socket 16 adapted to receive the inner end of a shaft 18, upon which pinions 19 and 2O are mounted and maintained in a spaced relationship by a collar or spacer 21, or otherwise. The shaft 1S also passes through and is journaled in a bearing 17, suitably fixed in the opposite wall of the housing 15. As illustrated, the bearing tube 17 terminates at its outer end in an enlarged exteriorly screw threaded head adapted to receive a packing nut 22 for the employment of a packing ring 23, to make a tight joint with the shaft 18.

he shaft 18 also passes into a gear casing 211, being journaled iny bearings 25 connected to the gear casing. Vithin the gear casing 24 the sh aft'18 is provided with a worm gear spending With the hearing sleeve 17.

26 adapted to mesh with a Worm 27 also Within the gear case 24, and secured to a shaft 28. This shaft 28 also passes through the gear case and is journaled in suitable bearings 29 connected thereto.

rlhe appara-tus includes a second gear case 30, similar in all respects to the gear case 24. The shaft 28 passes through this second gear case 30 and is journaled in hearings 81 carried therel'iy. At this end of the shaft 28 the same is provided With a hand Wheel 32, hy which, will he understood the shaft may he turned in either direction. Nithin the gear case 8O the shaft 28 is fitted with a Worm 38. rlhis Worin 33 meshes with a Worm, gear 83 mounted Within the gea-r case 3() on a shaft 84, Which corresponds to the shaft 18. rlhe shaft 34 is journaled in hearings connected with the gear casing 30, and is fitted With a packing nut 86, adapted to contain a suitable packing ring and to he turned down on the screw threaded head of a. hearing sleeve 37, corre- The shaft 34 passes into a housing 88 Where it is provided With pinions 89 and 40, corresponding with the pinions 19 and 20, respectively. The teeth of the pinions 89 and are adapted to enter the apertures provided in the apertured portion 12 of the wick holder, and in a similar manner the teetl of the pinions 19 and 20 are adapted to enter the apertures of the apertured portion 13 of the Wick holder.

It will now he understood that by turning the shaft 28, which may he considered a drive shaft in either direction, the shafts 84 and 18, which may be considered countershafts may he turned in opposite directions by arranging the Worms and Worin gears to so turn these shafts, and thereby impartthe necessary movement to the sets of pinions Si) and 40, and 19 and 20, to impart simultaneously to opposite sides of the Wick holder a uniform movement, therehy preventing the Wick holder from becoming wedged and effecting a uniform height of the Wick and a correspondinglyr uniform height of the flame is produced thereby in use.

By reference to TFigs. 5 and 6, it will he seen that instead of employing the Worm wheels and Worm gears the same oloj ect may he accon'iplished hy the use of spur gears. To this end the Wall l() in a suitable position is provided with a housing 41, extending into which there is a shaft 42. Mounted on this shaft are pinions 43 and 44, adapted to engage the Wiel; holder at one side thereof. rlhe shaft 42 passes through a sleeve hearing 45 and is fitted With a paoliing nut 46 for making a tight joint With the shaft. The shaft 42 also passes into a gear casing 47, the shaft being journaled` in suitable hearings 47 connected to the gear case. Within the gear case 47 the shaft 42 carries a spur gear 48. rlhis spur gearV meshes With a similar gear 49 carried by a shaft 50. The shaft 50 also extends into the gear case and is ournaled in a suitable hearing 5l connected thereto. The shaft 50 passes through a gear case 52, and is journaled in hearings 53 connected thereto. At the free end of the shaft 42 the same is fitted With a hand Wheel 54, by which the shaft may be turned in either direction. Mounted on the shaft 50 Within the gear case 52 is a spur gear 55. This spur gear 55 meshes with a similar gear 56 mounted on a shaft 57, passing into the gear case and journaled in bearings 58 connected thereto. On the shaft 57 there is a packing nut 57', and the shaft 57 passes through and is journaled in a hearing sleeve 59 connected to the housing` 60, secured to the Wall 10 in a position oppositely disposed to the housing 41. Vfithin the housing 60, the shaft 57 is fitted With spaced pinions 62 and extending through an aperture in the Wall 10 at this side thereof, so as to engage ti e apertured or rack portion 12 o-f the Wick holder on this side thereof. The parts of the apparatus in this construction as will he obvious, operate in a manner similar to those hereinhefore described, and are adapted to simultaneously effect a. uniform movement of the Wick holder from oppositely disposed sides thereof to prevent the same from Wedging, and to cause the Wick to evenly project in all portions thereof beyond the peripheral edge of the Wall 10, to obtain a uniform height in the flame from the Wick when the burner is in use.
